Mrs Luis baked
15 as many apricot croissants as cranberry croissants. She also baked
23 as many apricot croissants as apple croissants. If she baked a total of 90 croissants, how many apricot croissants did she bake?
Apricot |
Cranberry |
Apple |
1x2 |
5x2 |
|
2x1 |
|
3x1 |
2 u |
10 u |
3 u |
The number of apricot croissants is the repeated identity. Make the number of apricot croissants the same. LCM of 1 and 2 is 2.
Total number of croissants
= 2 u + 10 u + 3 u
= 15 u
15 u = 90
1 u = 90 ÷ 15 = 6
Number of apricot croissants
= 2 u
= 2 x 6
= 12
Answer(s): 12
